COIN-CONTROLLED MUSlC-BOXL SPECIFICATION forming part of Letters Patent No. 473,342, dated April 19, 1892.

Application filed December 16,1891. Serial No. 415,250. (No modeh) To all whom it may concern: Be it known that I, GEORGE RAAB, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and usefulv Ooin- Controlled Music-Box, of which the following is a specification.

This invention relates to coin-controlled apparatus, and more especially to that class thereof wherein the insertion of the coin causes the delivery ofa key; and the'object of the same is to provide a construction whereby the operating mechanism for the musical instrument may be Wound with the key and its retaining-pawl tripped by the replacing of the key.

A further object is to provide a guard over the key-hole to prevent the insertion and use of ordinary keys, and to provide means whereby the weighted lever cannot be operated by inverting the entire device.

Other objects and advantages will appear in the following specification and claims, wherein is set out at length a description of this improved device, to be taken in connection with the accompanying three sheets of drawings, wherein-- Figure 1 is a perspective view of this device ready for operation. Fig. 2 is a front elevation thereof with the door open. Fig. 3 is a similar View with the parts in position after the coin has dropped. Fig. tis apersp'ective detail of the trip-lever and key. Fig. 5 is a similar View of the slide and guard, showing the key-hole in dotted lines. Fig. 6'is a perspective detail of the retaining pawl, its spring, and the operating angle-plate. Fig. 7 is a sectional detail of the spring at the upper end of the chute, showingacoin thereunder. Fig. 8 is a vertiealsection on theline S 8 of Fig. 2, but with the door closed.

Referring to the said drawings, the general elements of this machine, designated by reference-letters, are as follows: C is the casing having a coin-insertion opening I. T is the trip-lever, which is operated by the coin. the slide released by the trip-lever and which moves a guard or fraud-preventer F away from the key-hole, and in its movement also throws out the key K. D is the driving mechanism, which can be then wound by the key;

Sis

and M is the musical instrument which is driven by this mechanism when the key is reinserted in its socket, whereby the slide is pushed back and its angle-plate operates the retaining-pawl P to release it from engagement with the musical instrument and allow the latter to run. The general cooperation of the elements as thus indicated is effected by their specific constructions, as hereinafter more fully described.

The casing C.This may be of any desired size and construction, preferably about as shown in the drawingsthat is to say, a rectangular body 1 is mounted on a base 2, a door 3 closing the front of the body and having a lock 4, and a top 5 is mounted on the upper end of the body by pins or screws 6, which are removable from the interior, so that after the door is opened the top can be taken off, as will be readily understood. Within the body are partitions 7 and 8, as may be necessary, to provide supports for the mechanism hereinafter described and to form a box or receptacle 9 for the coin.

The insertion-opening, spring, and chute I. Through the cover 5 is formed a slot over whose upper end is an escutcheon 10, having at one end enlarged guides 11, between which a coin can be passed, and 12 is a spring secured to the'cover at the other end of the escutcheon and havingaslot 13, registering with that in the cover, and a handle 14. WVithin the casing isa chute 15, which leads down to a point above the trip-lever T, whence acoin which is passed therethrough will be free to fall into the receiving-box 9.

The trip-lever T.20 is a bar or rod pivoted at 21 between its ends to a bracket 22, projecting from the back of the casing, one end of this rod having a weight 23 and the other end standing under the mouth of the chute 15. Near this end are two collars 24., adj ustable by means of set-screws 25, and 26 is a link clamped between the collars and hanging from the bar, the lower end of this link having a reduced notch 27.

The key KThe key proper comprises a cylindrical shank 30, having in one end a square hole 31, at the other end a head or knob 32, and its body being annularly grooved, as at 33. 34 is a socket passing through the and the pin 49 rests in the recess 48. dition to this plate, pins 52 rise from the guides 40, and a weight edloosely on said pins, the whole being 10- catcd on that side of the pivot 21 of the trip side wall of the casing in alignment with the slot in the link 26, and 35 is a ring-shaped rosette secured on the outside of the casing in position to embrace the head or knob of the key when in place so that said knob can not be grasped to withdraw the key. At the back of the casing is a key-hole 3", through which the shank of the key may be passed to engage its hole 31 with the driving mechanism.

The slide S.l3etween guides 40, mounted on the partition '7, moves a bar 41, forming the body of the slide, and this is drawn toward the link 26 by a contractile spring 42, which leads preferably through the link to an eye 47, mounted in the sidewall of the casing. In the upper face of the bar ll, near its other end, is formed a recess 48, in which is adapted to 'beseated a pin 49, which depends from the weighted end of the trip-lever, the length of parts being such that when the key K is pushed in the slide S is moved to permit the pin 49 todrop into the recess i8, and this will cause the link 26 to rise so that its notch 21 engages the groove 33 in the shank ofthe key; which at that time stands just in position.

The f2aucl-prercnteo' F.'50 is a plate secured to the body T1 of the slide'and leading down toa point 51, whichstands over the in ner end of the key-hole when the slide is in In adoa,having holes 54, is mountlever T opposite from the weighted end 23 of said lever. The first device or guard prevents a key being inserted in the key-hole un-, less the key Kis withdrawn, and the second device prevents the possibility of causing the trip-lever to operate by inverting the entire machine when the weight would move by gravity, because when so inverted the weight 53 moves on the pins 52 and holds the trip lever in its locked position.

The musical instrmnent llL-Iii the present case I have shown this instrument as consist. ing of a cylinder 60, having pins 61 in its face, and a comb 62, having fingers of graduated length, which are engaged by said pins, the whole forming what is popularly known as a music-box, but I desire to be understood as reserving the right of substituting any other well-known rendering-instrument which will operate in substantially the same manner and may be driven by a spring or weight. Connected with 't he cylinder is a gear (35, having holes or teeth 66 in one end or face, as shown.

The driving mechanism D -I have shown in outline a spring-actuated clock mechanism having a driving-gear 70 meshing with the gear 05 on the musical instrument, and also having a fan 71. geared thereto for rapid rotation to regulate the movements of parts, a squared shaft 73 on the winding-arborstanding opposite the keyhole 3t and adapted to be wound by the key.

The recvmingqaa'wZ P.From the slide S depends a rod 80, which passes through the partition 7, and secured to the lower end of this rod is an angle-plate 81, whose lip 82 is adapted to engage the upper end of a pawl 83. The latter is pivoted at 8% between its ends and is drawn against the operation of said lip by a spring 85, while its opposite (and in the present instance lower) end has a tip or finger 88, which by the spring is thrown normally into engagement with the holes or teeth (36 on the gear 65, so as to check the rotation of the cylinder 60 of the musical instrument.

Vith the above construction of parts the operation of my machine is as follows: The device being prepared for use and its door locked, it is left in a conspicuous place, ac-

companied, of course, by signs to attract the notice and to give instructions anddirections for use. The customer approaching places a coin in the insertion-opening I, passing it between the guides 11 and seating it in the slot- 13 in the spring 12, as seen in Fig. 7. The handle 14. is then depressed,wl1ereby the coin is shot with considerable force through the escutcheon 10 and down the chute 15 and passing out the lower end thereof it strikes the trip-1ever T, turns it on its pivot, thereby releasing the slide, whose spring &2 draws it toward the socket 3i, and as the link 26 disengages the key K when the lever descends the movement of the slide will throw the key, with itshead, beyond the rosette, as seen in Fig. 3. Following instructions. the customer then takes the key out, passes it into the key-hole 3C-,and winds the driving mechanism. The movement of the slide causes the angle-plate 81 to move so that its lip 82 disengages the retainin g-pawl, the spring 85 then throws the finger 88 of the pawl into engagement with the holes or teeth (56 on the gear 65, and hence when the customer commences to wind the driving mechanism the musical instrument is held against movement, so that the winding does not cause the running of the machine. After the driving mechanism is wound tightly the key is withdrawn and replaced in its original position, as seen in Fig. 2. As this is done, the slide is pushed back, so that the pin of the trip-lever falls into the recess and the link rises to re-en gage the groove in the shank of the key; but the return movement of the slide causes the lip of the angle-plate to trip the retaining-pawl and the musical instrument is then free to run under the stored force of the driving mechanism. WVhen this energy is expended that is,when the machine has run down-the tune or tunes will have been finished,and the abovedescribed operation mustbe repeated in order to work the instrument further.

The sizes and shapes of the parts shown may be varied to a considerable extent without departing from the spirit of my invention, and the machine is susceptible of a considerable degree of modification and elaboration both in its details and in some of its essential features, two of which are indicated above. The ornamentation and-finishing of the machine are matters of taste.

For the sake of clearness I will state that the word rendering, as herein used, refers to that portion of my machine which renders a return for the money paid. In the present case a musical instrument M is described and shown as connected with and driven by the driving devices D but, as above stated and as will be understood, this musical instrument may be replaced by vending mechanism to sell small articles or liquids which are delivered by the machine to the customer, or measuring mechanism and the like which will measure his weight, height, strength, or lungcapacity, or which will take his photograph, tellhisfortune, or do such other things as are well known in machines of this class.
